Relais Board


Double, tripple or quad relais module from dx.com, Alibaba or Amazon


1. Using 5 V control voltage from Arduino


For 5 V systems like ArduinoKeine Zugangsberechtigung connect Vcc to 5 V and set the JD-VCC jumper.

The inputs are low-active. The microcontroll must deliver a low level to activate the relais.




2. Using 3.3 V control voltage from Raspberry Pi


For 3.3 V systems like Raspberry Pi remove the JD-VCC jumper. Conect 5 V to the JD-VCC side of the jumper.
Connect 3.3 V to VCC.

4. Relais ratings




SRD-05VDC-SL-C says
  • SRD: relais model
  • 05VDC: Voltage the relais coil should be 5 V (this is JD-VCC)
  • S:Sealed type
  • L: coil power consumption is 0.36 W
  • C: Contact form type C


10A 250VAC 10A 125 VAC says: The voltage at the relais contacts should not exceed 250 V and 10 A for alternating current

10A 30VDC 10A 28 VDC says: The voltage at the relais contacts should not exceed 30 V and 10 A for direct current


5. Power consumption


71.4 mA was found in the data sheet.
I was measuring 80 mA per channel when active (relais on).
